The victim of the attack is still having trouble seeing through one of his eyes, MBTA spokesman Richard Sullivan said in an e-mail.

In the wake of the attack early Sunday morning, Transit Police circulated pictures of the juvenile, Douglas, and another woman allegedly involved in the assault and robbery on a Route 28 bus on Blue Hill Avenue in Dorchester.

Transit Police are still asking for the public’s help in identifying the other woman involved in the attack.
